See the `mcu` folder of the [nix-scripts repository](https://git.m-labs.hk/M-Labs/nix-scripts).
|
Thermostat firmware is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2.4+ and enable flakes by adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (e.g. ``~/.config/nix/nix.conf``).
|
||||||
|
|
||||||
|
Once you have Flakes enabled, you can use ``nix build`` to build the firmware.

## Fan control
|
||||||
|
|
||||||
|
Fan control commands are available for thermostat revisions with an integrated fan system:
|
||||||
|
1. `fan` - show fan stats: `fan_pwm`, `abs_max_tec_i`, `auto_mode`, `k_a`, `k_b`, `k_c`.
|
||||||
|
2. `fan auto` - enable auto speed controller mode, where fan speed is controlled by the fan curve `fcurve`.
|
||||||
|
3. `fan <value>` - set the fan power with the value from `1` to `100` and disable auto mode. There is no way to completely disable the fan.
|
||||||
|
Please note that power doesn't correlate with the actual speed linearly.
|
||||||
|
4. `fcurve <a> <b> <c>` - set coefficients of the controlling curve `a*x^2 + b*x + c`, where `x` is `abs_max_tec_i/MAX_TEC_I`, a normalized value in range [0,1],
|
||||||
|
i.e. the (linear) proportion of current output capacity used, on the channel with the largest current flow. The controlling curve is also clamped to [0,1].
|
||||||
|
5. `fcurve default` - restore fan curve coefficients to defaults: `a = 1.0, b = 0.0, c = 0.0`.
